Next door house for sale but wife and I just purchased! SOS

[Andrew May]

My wife and I purchased our first home three weeks ago in May. The location is perfect for renters so our plan is to rent our home out in a year. In addition, the house next door is going to be for sale soon. We would love to jump on the next-door home but our cash flow is very low right now. Plus, our current loan requires us to live in our current property for a year, so an FHA won't work to acquire a second mortgage. Any ideas or suggestions would be wonderful.
